TYPE-WRITING MACHINE.

To all whom it may concern Be it known that I, LEWIS C. MYERS, a citizen of the United States of America, residing in the borough of Brooklyn, city and State of New York, have invented certain Improvements in Type-VVriting Machines, ofwhich the following is a specification.

This invention relates to a novel form of card holder or clamp applied t0 a front strike visible machine such, for instance, as the Royal Standard.

It comprises a card' holding plate detachably mounted in or upon the machine between the surface of the platen and the usual vertically vibrating ribbon guide. This card holding plate is constructed and located in such way as to hold the card at the printing point against the platen so that printing may be impressed upon the card close to any of its edges.

In the accompanying drawings: Figure 1 is a front elevation showing the platen, paper feed and clamping devices, etc., and my improved card holder: Fig. 2, a top plan view of what isshown in Fig. 1: Fig. 3, a side elevation showing someof the shafts in section: Fig. 4., a frontelevation of the card guide detached: Fig. 5, a detail view showing one way in which the card guide may be used: Fig. 6, a similar view indicating the feeding of a card in full lines and the final passage of the card from the platen in dotted lines: Fig. 7, a like view showing a card with its lower edge substantially at the printing line: Fig; 8, a detail view showing one corner of the card holder plate provided with a socket for receiving a vertical pin at the end of the segment plate Fig. 9 is a front elevation, and Fig. 10, a side elevation of the type bar guide: Fig. 11, an end elevation: and Fig. 12, a front elevation of the modification, of the card clamp, that is indicated in Fig. 8.

The drawings show a paper table a, paper pan 1), rear feed rolls a, front feed rolls d, vertically movable scale 0 that may be moved up to the line of print when the feed rolls are thrown off. The feed rolls are thrown away from the platen andthe scale bar moved to the printing point when shaft f is partially rotated, the pivoted arms or levers carrying the feed rolls normally lie in transverse notches in the shaft and when the shaft is rotated they are forced up on the high part, that is to say, upon the pe- Specification of Letters Patent.

riphery of the shaft and the feed rolls are then withdrawn from the platen.

9 1s a rotatable shaft operated through the release lever (not shown) to move the scale bar to the printing point at the time the feed rolls are thrown olf,-that is to say, 9 1s a rock shaft having a forwardly proecting curved arm g at each end and to the 'ends of which are pivoted upwardly extendlng arms 9 in the upper ends of which lower corners of the vertically disposed card clamps or guide l: or, as shown in Fig. 8, the card clamp or guide Z may be formed with sockets It, to recon-e pins extendlng up from the segment.

at indicates a well known form of type bar guide and n a well known form of ribbon vibrator located in rear of the guide.

Between the printing surface of the platen 0 and the rear of the ribbon vibrator is located the card holder Z that may be ap propriately mounted in any suitable way upon the machine, as, for instance, in the ways shown in Figs. 1 and 8.

On the lower plate of the type ,bar guide at each end or side thereof is an upright projection 19 that may be turned inwardly or rearwardly sufficient to bear against the lower edge of thecard holder Z and hold it ,out of contact with the ribbon vibrato-r.

The card holder is shown detached in Fig. 4 in front elevation and in top plan in Fig. 2. It comprises a flat plate to which the letter 1 has been applied. lts upper edge has in it an oblong recess 9 of suitable width and of sufficient depth to accommodate the 100 type bar heads;that is to say, to permit the type to make impact against the platen. To the right and left of this opening g,,the plateis formed with openings 1', '1', which are preferably triangular in shape, as shown, or 105 otherwise, and the plate at the straight bottom edges of these. openings is engraved with a scale s. The small tongues or projections t formed of the sheet metal of which the card holder plate is formed and project- 110 Other paper clamps z are also ing into the openings 1', serve to prevent an inserted card envelop or sheet from entering either of the openings or striking against the edges. or walls thereof. The metal forming the edges of the openings 1* is thrown out as indicated at r to stiffen the plate and form rounded rear edges that will I not tend to hold or impose any drag upon the card as it is passed around the platen. Beyond the flat central portion of the plate having the openings 1", r, the plate is formed with lateral extending wings u that are de- 'fiected to the front as seen in Fig. 2, the

point of deflection or bend being indicated 5 by the line u"in Fig. 4. The manner in the ordinary way under the clamp rolls h.

The apertures or openings 9" allow inspection of the printed matter upon the card and also facilitate alining of the card by the operator.

The forwardly obliquely disposed wings it serve to guide the card into position if it be introduced either under the platen or backwardly over thetop of the platen to one side of the central part of the card holder (Fig. 6) so that when the carriage moves laterally, the card will pass accurately behindthe central part of the cardholder and be held closely against the platen.

The clamping rollers h Figs. 1, 2 and 3,

act. to hold a card from above so that its lower part, that is pressed against the platen by the holder Z, may be printed upon close to the bottom edge. When required these rollers may be thrown back out of the way as indicated in Fig. 3.

I claim:

1. A card guide adapted to be mounted between theribbon vibrator and the printing surface of the platen of a front strike typewrit-ing machine, comprising a flat plate with a recess opposite the printing point on the platen through which the types impact against the platen, apertures on each side of said recess having straight bottom edges engraved with a scale and forwardly obliquely disposed side wings for deflecting an insert ed card into position between the central fiat part of the plate and the printing surface of the platen.

2. A card guide adapted to be mounted between the ribbon vibrator and the printing surface of theplaten of a front strike typewriting machine, comprising a flat plate LEWIS O. MYERS.
